Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

2020 Cadillac CT5 debuts at N.Y. Auto Show as a proper sport sedan

The 2019 Cadillac CT5 is here, and it's not a tweener sedan. After having done battle with the luxury sedan world through cars that were either too large or too small, Cadillac is using the CT5 to take direct aim at the BMW 3 Series, Audi A4, Alfa Romeo Giulia and Mercedes C-Class. Specifically, the CT5 replaces the CTS, but takes on vehicles one class smaller than what the CTS did. So, let's take a look at what Cadillac is bringing to the table. To begin, GM knows it has a winner on its hands with the Alpha platform used on the CTS and ATS and the Camaro, so engineers adapted it to the CT5. This seems like a great start, because we all happen to love the driving dynamics from vehicles on this chassis. The wheelbase is a couple inches longer than the CTS, but the CT5 is a couple inches shorter in overall length. As a result, the wheels get pushed toward the corners of the car, leaving the CT5 with relatively short overhangs in the front and rear. It looks different than both of the to-be-discontinued Cadillac sedans, but we wouldn't call it revolutionary. The rear end isn't quite a "sportback," but it's a "faster" shape, eschewing a traditional sedan's long decklid for a sloping-roof look instead. This shape does come at the expense of rear seat headroom, but we'll dive into the interior later. We got a little preview of the powertrain setup before this official reveal, but details were scarce. The base engine is the recently new 2.0-liter turbo four-cylinder found in the Cadillac XT4. Just as it did in that vehicle, this engine makes 237 horsepower and 258 pound-feet of torque. While it might be down on power compared to the old 2.0-liter in the ATS (272 horsepower and 295 pound-feet) we found it to be incredibly smooth, refined and not lacking in thrust compared to the old unit. We're sure the four-pot will offer sufficient power for the CT5, but the 3.0-liter twin-turbo V6 is lying in wait. This engine makes 335 horsepower and 400 pound-feet of torque. Both engines are paired to a 10-speed automatic transmission and can be had in rear-wheel drive or all-wheel drive in every configuration. So yes, you can get the V6 with rear-wheel drive, thankfully. Cylinder deactivation is also equipped to both these power units — the four-banger is able to run on two cylinders, while the V6 drops to four. Cadillac was entirely transparent about its new pumped-in engine sound strategy, too.
